Abstract: The present disclosure is drawn to 3D printing kits and methods of making 3D printed articles. In one example, a 3D printing kit can include a powder bed material, a fusible fluid, and an activator fluid. The powder bed material can include polymer particles. The fusible fluid can include a radiation absorber. The fusible fluid can be to selectively apply to the powder bed material. The activator fluid can include a non-conductive electroless metal plating activator. The activator fluid can also be to selectively apply to the powder bed material.

Abstract: In an example, a method includes operating, by a processor, on object model data. The object model data describes at least part of an object to be generated in additive manufacturing. The method also includes determining, by a processor, pattern data. The pattern data comprising areas of variable reflectance intended to be formed on a portion of the object. The method includes determining, by a processor, object generation instructions to apply a fusing agent to at least part of a layer of build material corresponding to the portion of the object in a density corresponding to the reflectance of the generated pattern data.
